Dear Insight,
the sclera of the eye works the same as the iris and has a slightly different chart.
9 O'clock in left eye is low larynx and cough reflex. above that you find the thyroid and below 9 the oesophagus. Depends on how straight the vein is. If it meanders it affects all three areas. Sclera is more acute than iris. Is the eyeball painful? Is there an orange raised pterigeum/pinguecula at or below thw area? Indication of Hormonal imbalance/gallbladder imbalance. There are many questions. I would like to see an image of the area to do justice. Go and see a naturopath that does iridology and sclerlogy.
Spiritually the thyroid has to do with Anger.
and the from 8 to 9 o'clock you find Fear.
Have you got issues in those areas?
Look at you diet and what you do to your body. Red sclera can be a sign of a number of things.
Hope this helps.
